The stress of the shifting cargo is received by the longer corrugations and transmitted to the flat plate at 12 and thence to the adjacent corrugations on either side of it, which in turn, transmit the stress to the web. rlhe remaining portion 13 of the continuous web extends-continuously and unin- This web receives the load from'rthe corrugations and forms a beam or stiffener to prevent bulging in transmitting the load from the corrugations to the frame of the car.

The corrugations may be of greater or less depth than the depression forming the continuousweb but are offlessdepth than the web v5 which theyY merge into it; in other words, they merge into a portion of the web. The marginal portion 4 (or portions) may be provided with stiften the sidesoffthe door against deflection under load land to stillen the entire door p against buckling or distortion.
